CALL-BELL.

fiPECl'PEGATION forming part of Letters Patent No. 330,756, datedNovember 17, 1885.

Application filed October 12, 1865. Serial No. 179,638. (No model.)

To all whom it may concern:

Be it known that l, WALDo L. UPSON, of Meriden, in the county of NewHaven and State of Connecticut, have invented new Improvements inCall-Bells; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure l, a vertical central section of the bell, showing front view ofthe operative mechanism; Fig. 2, the same, showing side view of themechanism; Fig. 3, adetached View of escapement-wheel arbor, showingescapementwheel and ratchet in section; Fig. 4, a rear view of theescapementwheel, pawl, and ratchet; Figs. 5 and 6, modifications.

This invention relates to an improvement in that class of call-bells inwhich the bell is arranged upon a post with a spindle extending downwardthrough the bell, and so that pressing the spindle down causes thehammer to strike the bell.

The object of this invention is to arrange the parts so that by pressingthe spindle down once will cause the hammer to strike the bell severaltimes; and it consists in the arrange- 1nent,as hereinafter described,and particularly recited in the claims.

A represents the base; B, the post extending upward from the base.

0 is a plate which with the post forms the frame for the operativemechanism. The said plate is constructed with a vertical slot, a.

D is the bell, adapted to be secured to the upper end of the post in theusual manner. Within the frameis ahorizontal arbor, 1;, upon which isfixed a ratchet-wheel, (2. Loose upon the arbor b and close to theratchet-wheel d is an escapement-wheel, e.- A pawl, f, is hung upon oneside of the escapement-wheel e, as seen in Figs. 3 and 4, and isarranged so that the teeth of the ratchet-wheel will engage it whenrevolved in one direction, and to escape when revolved in the otherdirection, and to the arbor a pinion, g, is fixed E is a spindle, whichextends vertically through the bell in the usual manner, and isconstructed with a toothed rack, h, at its lower end, adapted to engagewith the pinion g, and is provided with a pin, 70, extending through theslot (0 in the plate 0, which guides it in a vertical path. Aspring, Z,is arranged in connection with the spindle E, the tendency of which isto raise and hold the spindle in its up or normal position.

F is a hammer hung upon an arbor, m, in the frame, parallel to the arborb, and upon said arbor m is a verge, n, adapted to engage with theescapement-wheel e, as in alarmclocks.

To cause the bell to be struck, press the spindle down, and, guided bythe pin it in the slot (1, the teeth on the rack will engage with thepinion 9, thereby revolving the arbor b and ratchet-wheel (Z, whichcauses the teeth of the wheel (I to engage with the pawl f, and therebyimpart revolution to the escapement-wheel e, which by so revolving actsupon the verge n and causes the hammer to vibrate and strike the bell.\Vhen the pressure on the spindle is removed, the reaction of the springlcauses it to rise to its former position. In rising the rack revolvesthe arbor b and ratchet-wheel d in the opposite direction, and in whichthe ratchet-wheel escapes the pawl f and allows the escapement-wheel eto remain stationary.

To hold the escapement-wheel 0 against the ratchet-wheel d and supportit loose on the shaft, a friction-collar, o, is introduced in the usualmanner for such devices in clock-work.

If desired, the ratchet-wheel may be omitted, the escapement-wheelsecured to the arbor, and the verge made the same at both ends, as shownin Fig. 6, so that the return of the spindle will cause the bell toring.

The frame to support the mechanism may be made separate from the post B,as shown verticallyguided spindle E, extending upward through the bell,its lower end provided with a toothed rack corresponding to said pinion,

IOO

and so as to work therein, a second arbor, m, carrying a verge andhammer, with a spring adapted to raise the spindle and support it in itsup position, substantially as described.

2. The combination of the base A, the post B thereon, the plate 0, fixedto said post, and with the post forming a frame, the bell D, secured tosaid post, the vertically-guided spindle extending upward through thepost and bell, constructed at its lower end with atoothed rack, thearbor b, arranged in said frame, and carrying the pinion g and toothedratchet d, both fixed to the arbor, the escapement-wheel a, loose uponsaid arbor, with a pawl on said escapement-wheel adapted to be engagedby r 5 the said ratchet-wheel in one direction, but escape therefrom inthe opposite direction. the second arbor, m, carrying the verge andhammer, and a spring in connection with said spindle adapted to raiseand hold it in its up 20 position, substantially as described.
